Zuag qhia tag nrho
P235TR1 yeeb nkab yog aseamless, tsis yog -alloy steel tubetsim los siv rau hauv boilers, siab hlab ntsha, thiab lwm yam siab - kub thiab siab daim ntawv thov. Nws cov yam ntxwv tseem ceeb yog weldability zoo, lub zog ntawm qhov kub thiab txias, thiab lub siab ntim.
TS EN 10216-1 Kev Nyab Xeeb Kev Nyab Xeeb
Txoj cai "P235TR1" yog txhais los ntawm European tus qauvTS EN 10216-1: Seamless steel raj rau lub hom phiaj siab - Cov txheej txheem kev xa khoom - Ntu 1: Cov hlau tsis muaj hlau tsis muaj hlau nrog cov khoom ntsuas kub hauv chav.
Nov yog qee qhov ntawm qhov chaws txhais tau li cas:
P: Sawv rau"siab", qhia lub raj lub hom phiaj siv.
235: Qhov no yogYam tsawg kawg nkaus yield zog (ReH)ntawm chav sov, hauvMPa(MegaPascals). Qhov no txhais tau hais tias cov yeeb nkab muaj lub zog tawm ntawm yam tsawg 235 MPa (los yog kwv yees li 34,000 psi).
TR: Sawv rau"Tube"raws li European standardization system.
1: Qhov no yogqib khoom siv. Qib 1 muaj kev txwv tshuaj lom neeg tshwj xeeb, tshwj xeeb tshaj yog rau cov pa roj carbon, phosphorus, thiab sulfur, uas ua rau nws haum rau vuam thiab siab - qhov kub thiab txias.
Cov yam ntxwv tseem ceeb & Khoom
1. Chemical Composition (Hom rau Qib 1)
Cov muaj pes tsawg leeg yog tswj los xyuas kom meej weldability thiab lub zog.
Cov pa roj carbon (C):Max ~ 0.16% - Cov ntsiab lus carbon tsawg kom ntseeg tau zoo weldability.
Manganese (Mn):Max ~ 1.20%
Phosphorus (P):Max 0.025% - Tsawg P & S txhim kho toughness thiab weldability.
Sulfur (S):Max 0.020%
2. Mechanical Properties ntawm Chav Kub Kub
Yield zog (ReH):Ntau dua lossis sib npaug li 235 MPa
Tensile zog (Rm):360 - 480 MPa
Elongation (A):Nws txawv nrog thickness, tab sis feem ntau ntau dua los yog sib npaug rau 25% (qhia tau zoo ductility)
3. Siab Ua Haujlwm
Cov yeeb nkab yog tsim los tiv thaiv sab hauv. Nws qhov ntsuas siab tuaj yeem suav nrog cov qauv zoo li EN 13480 (rau cov kav dej) lossis ASME B31.1 (rau cov kav dej fais fab), siv cov qauv uas suav nrog cov khoom muaj zog, phab ntsa tuab, thiab sab nraud.
Cov ntawv thov siv
P235TR1 cov kav dej yog siv rau hauv cov tshuab uas muaj kev nyab xeeb thiab kev ntseeg siab nyob rau hauv siab thiab kub yog qhov tseem ceeb:
Boiler Tubes:Rau ob qhov hluav taws kub- raj thiab dej- raj boilers.
Superheaters thiab Kub Exchangers:Qhov twg qhov kub siab tshaj tab sis tsis siab heev.
Cov nkoj siab:Rau muaj cov pa roj los yog kua hauv lub siab.
Fais fab Generation Plants:Hauv chav dej thiab chav dej.
Industrial Txheej Piping:Hauv tshuaj, petrochemical, thiab cov chaw tsim khoom.
Sib piv nrog Lwm Qib
Nws yog qhov pab tau kom pom tias P235TR1 piv rau lwm cov qib boiler / siab raj qib:
| Feature | P235TR1 (EN 10216-1) | P235TR2 (EN 10216-1) | A53 / A106 Qib B (ASTM) |
|---|---|---|---|
| Txuj | Teb chaws Europe (EN) | Teb chaws Europe (EN) | Asmeskas (ASTM) |
| Min. Yield zog | 235 MPa rau | 235 MPa rau | 240 MPa (A106 B) |
| Qhov txawv tseem ceeb | Standard cuam tshuam cov khoom ntawm chav tsev temp. | Guaranteed tej yam khoom ntawm qhov kub thiab txias(-10℃lossis qis dua). | Common US tus qauv rau kev dav dav thiab siab -temp service. |
| Kev siv yam | General boilers, siab systems. | Cov kab ke uas tsawg -kub toughness yuav tsum tau. | Ib qho dav dav heev - lub hom phiaj siab yeeb nkab. |
Nco tseg:P235TR2 yog ib qho kev pom ntau dua li P235TR1 vim tias nws muaj kev ruaj ntseg zoo, muab kev nyab xeeb dav dua.
Cov ntsiab lus tseem ceeb rau kev siv
Kub txwv:Thaum zoo rau qhov kub siab, P235TR1 yog atsis yog - alloyhlau. Nws lub zog txo qis dua li ~ 450 degree. Rau qhov kub siab dua, cov hlau hlau zoo li P91 lossis P92 yog siv.
Corrosion Resistance:Nws yog carbon steel thiab yuav xeb yog tias tsis tiv thaiv. Nws tsis haum rau cov cheeb tsam uas muaj corrosive heev yam tsis muaj kev tiv thaiv txaus (xws li, pleev xim, rwb thaiv tsev).
Certification thiab Test:Cov kav dej xa mus rau EN 10216-1 tau dhau qhov kev sim tsis muaj kev puas tsuaj (xws li ultrasonic lossis eddy tam sim no), kev ntsuas hydrostatic, thiab kev tshuaj xyuas tshuab / tshuaj xyuas kom ntseeg tau tias lawv ua tau raws li tus qauv.
Weldability:Nws cov pa roj carbon tsawg sib npaug ua rau nws yooj yim heev rau vuam siv txhua txoj hauv kev, tab sis cov txheej txheem vuam txheej txheem rau carbon hlau tseem yuav tsum tau ua raws.
Cov ntsiab lus
P235TR 1yog ib qho kev ntseeg siab, dav dav - lub hom phiajseamless carbon steel yeeb nkabtsim rausiab thiab siab -kub sivzoo li boilers thiab tshav kub exchangers. Nws lub npe qhia rau koj txhua yam txog nws qhov tsawg kawg nkaus lub zog (235 MPa Yield), nws lub hom phiaj (Pressure Tube), thiab nws cov khoom qib (1), kom ntseeg tau tias nws ua tau raws li cov kev cai tshwj xeeb ntawm European EN 10216-1 tus qauv.
